What type of transmission fluid does the chevy impala use?

The Chevy Impala uses DEXRON-ViAutomatic Transmission Fluid. The fluid level does not need to be checked regularly, only if a leak is found or suspected. Car manufacturers have made it so difficult these days to check and change the transmission fluid, You're forced to either take it to the dealer or repair shop. The Impala does not have a typical transmission dipstick. The car has to be level and lifted to access the drain and fill plugs. The transmission holds about 6.3 quarts and is full when the fluid is at the bottom of the fill plug threads. You should have the fluid changed every 30,000 to 50,000 miles or five years.
